Problems solved by technology

Even if the same product from different manufacturers is applied to different manufacturers, there are cases where the effect is quite different
Existing products cannot give full play to the product’s effect of improving the adhesion of grinding materials, and fail to combine various effective grinding aid ingredients together to achieve the best grinding effect. At the same time, chlorine or alkali in existing grinding aids will Hazardous to cement or concrete

Abstract

The invention discloses a cement grinding aid, comprising calcium formate solution, compound glycerol distilled residue solution, triethanolamine, diols and molasses. While the product reutilizes the industrial wastes, the components of the product synergistically act to optimize the efficacy of the grinding process and the product modifies the cement particles, thus improving the quality and performance of the cement while improving the cement yield and saving electricity, and the product does not only have grinding function.

Description

Technical field [0001] The invention belongs to the field of cement production, and specifically relates to a cement grinding aid material. Background technique [0002] Since the 1930s, the British Goddard used resin as a grinding aid and obtained a patent. Afterwards, people successively experimented with grinding aids such as acetic acid, phosphate, lignosulfonate, ethylene glycol, phenol, triethanolamine, tung oil and asphalt. In the 1960s, industrial developed countries such as Japan, the United States, Germany, and the former Soviet Union had more and more extensive research and application of grinding aids. In some developed countries, almost all cement plants used grinding aids. Compared with China’s The research and utilization of grinding agents started relatively late. In the late 1950s, only a few cement plants tested the use of coal, paper pulp waste liquid, and soap waste liquid, but the effect was not very obvious. At present, domestic research and application of ...
